Compumask transmitter

[kydaka]

I just purchased a Compumask and transmitter and I cannot for the life of me figure out which of the 10 number serials are the 5 numbers I need to snyc the two together. Why would any sane company put a 10 number serial number on this and ask for 5 number input and not say anywhere in the manual which numbers to use........frustrated

I think it is the last 5 I don't remember having this problem, love the mask.

Yep, I've got the Oceanic Datamask, which is the same thing and it's just the last 5.
